How a runner can go further in less time at the same speed.

When movement is in a faster time frame, time dilates.


Relativity causes movement in a faster time frame to dilate time, either for an astronaut or for a stimulus response signal in human nervous system. Time dilation is explained below.
Einstein did a thought experiment about a spaceship. An astronaut inside it flashes a pulse of light perpendicularly across the spacecraft, setting off a timer and reflecting back from a mirror to the timer again. The travel time across the width is T seconds read from the timer.’
If the spaceship moves forward at the speed of light, would the travel time T across the spaceship and back be the same as when it was stationary?’
If we could look inside through a porthole using a telescope from Earth, we would see the path of the light pulse illuminating dust particles in the air along a diagonal path to the mirror in its new position, being reflected off the mirror and coming back along another diagonal, completing a dogleg.
Can the light pulse still go across in T? It has three conditions to obey. 1. The diagonal path is further than the path perpendicularly across; 2. It must arrive by the same time T; and 3. It cannot go faster than the speed of light.
It can’t, because to go further along the diagonal in the same time, it would have to go faster. But if it was already at the speed of light and couldn’t go faster. Nor could it arrive after the time the astronaut would observe.
Therefore it would be impossible for the pulse to be seen at the same time. Einstein supposed time would dilate or stretch. If each second lasted longer, it would make sense. We are used to a pendulum beating out constant aliquots of time but at high speeds it would have to beat more slowly and because each second would be longer, the longer distance could be travelled in fewer seconds.
Next in this series it is shown how time dilation for a person in a much faster time frame would cause a higher speed of travel.
My fiction novel Time is Gold, to be published shortly, tells how an athlete exploits metaphysics and wins.

Coffee changing minds?

cicerostatue

Cicero, 106-43BC, a Roman statesman, is reputed to have been the greatest orator ever. He said the three most important features of any speech are delivery, delivery and delivery. He used 16 devices bracketed in my illustrative piece below, designed for post Truth consideration, with apology to science adherents.

COFFEE – A PERSUASIVE SPEECH

The smell, the taste, the ritual, the warmth of the cup, the feeling of joy in my heart when I take that first sip. Since the 9th-century, coffee has been taken as a stimulant, sometimes addictively. It activates the heart and nervous system with hormones, to increase alertness.

Does meeting with friends at a cafe need the superficial and frenetic verbal intercourse that coffee causes? (Loaded emotional language) What do we lose when we hide our true feelings? (Fearmongering). Do we need life au naturel or hyped up with coffee?

‘Tired, stressed and depressed (Rhyme), coffee props your eyes open and helps you stay alert in a bad situation. Coffee keeps you going, holds your frazzled mind together, enabling you to play the game, get that raise and survive until the next holiday. When you lack energy and are straining to stay on top, you doubt you can manage without it. (Appeal to emotions).

‘I have a coffee addiction,’ said Jennifer Garam in Psychology Today. ‘I am doing a coffee detox one day at a time.’ (Testimony)

The 200 billion dollar coffee retail and supply industry would stop addictive qualities or harmful effects being publicised without conscience. (Mud slinging) There seems to be no legal obligation to display warnings on products other than pharmaceuticals.

Production of 10 millions tonnes per annum of coffee is not without its problems. The demand of coffee addicts (Labelling) commands prices for coffee beans that farmers in developing countries find irresistible. (Exaggerated). Tropical forests should not be felled to grow coffee. Would the Gods want us to sacrifice so much for so little? (Appeal to Gods or religion). Forest should be preserved, with the best fertile land and water going to growing rice and other grains. Lesser land should be used for dairying and grazing. The growing of foods should have priority over coffee.

Marijuana gives more buzz per hectare than coffee, requiring less land and less water. Coffee is expensive. Dollar for dollar, coffee swallows up to 30% of family grocery bills but contributes nothing to family nutrition, hygiene or health. Coffee is a scourge of humanity and should be rejected in the same way that tobacco has been (Guilt by association) and sugar will soon be (Divert and distract).

But coffee can be an instrument of revenge. Nancy Astor, Britain’s first female MP, told Sir Winston Churchill that: ‘If I were your wife I would put poison in your coffee.’

Churchill famously replied ‘Nancy, if I were your husband, I would drink it.’

To save ourselves we need to denounce coffee as a poison. I call upon all coffee drinkers to wake up to coffee’s effects and reduce their consumption before it is too late.

What if a man’s or woman’s assets are more/less?
My satirical novel ‘Short of Love’ explores unusual and amusing ways differences can be resolved and what can go wrong.

A.I. Smart or Dumb?

th-3

AI has focussed on algorithms for robots to mimic human behaviour. Imitation is prevalent for young children, but for teenagers and adults much learning is by trial and error, insight and critical thinking. They solve problems, make comparisons, judge situations, synthesise and create. AI would have to recognise what situation to imitate with its algorithm, without dumbing itself out of business. If you want smarts, use a human.
